I .UBRICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 626,166, dated May- 30,1899.

Y Application filed March 13, 1899. Serial No. 708.872. (No model.)

.To @ZZ whom 12m/ay concern:

Beitknown that I, LEOPOLD KAO'ZANDEE, a citizen of the United States,and a resident of the city of New York, in the county and State of NewYork, have invented certain new and useful Improvements in LubricatingApparatus, of which the followingis a specification.

This invention has for its object to provide a. simple and efficientmeans for lubricating steam cylinders and valves, especially those whichare subjected to variable steam-pressures, as is the case with thecylinders and valves of locomotive-engines. l

More particularly the invention is an improvement upon that class voflubricators of which the lubricating apparatus set forth in Swiftspatent, No. 272,793,0f February 20, 1883, is the type-i. e.,a-lubricating apparatus in which a choke-plug-or a contracted or chokedpassage is employed at or near the steam-chest of the engine tointercept to a great extent the pressure from either the steam-chest orthe lubricator and to equalize said pressure in the duct or pipe whichconveys the lubricant from the lubricator to the steam-chest, with theconsequent effect of equalizing also the flow of the lubricant. It hasbeen found in connection with such lubricating apparatus that the chokedpassage at the steam-chest is liable to become clogged, thus renderingthe lubricator inoperative, and different means havejbeen proposed forthe purpose of cleaning and opening up the choke plug in case ofclogging. means are either inconvenient or dangerous, as they requirethe stopping of the locomotive and consequent delay or mechanicalmanipulation on the part o f the enginemen while the engine is running.Toobviate these objectionable features of devices now known to me, Ihave perfected an improved steam-chest device in connection with thelubricator Whichniakes a clogging of the choke-plug during the run ofthe engine practically impossible.

I will first describe my improvements by reference to the accompanyingdrawings and will then point out more particularly in the claims thosefeatures which I believe to be new and of my o wn invention.

In the drawings, Figure 1 is a side eleva- All` such tion of so much ofa locomotive boiler, cylinder, steam-chest, and lubricating apparatus asis needed to illustrate my improvements.

Fig. 2 is an'enlarged vertical central section 55 of the steam-chestattachment in which my improvements are embodied.

A represents the boiler of a locomotive, B

supply pipe of the lubricator; F, the sight- 7o feed glass; G, thesteam-tube, which from thel top of condenser H conveys live steamthrough passages inside of the lubricator into oil-pipe I, the steamfrom the tube G and the oil from glass F passing together through pipe Iinto the steam-chest. The construction of such lubricators and thecooperation and function of the several parts composing the same arewell known and need no detailed description.A To the top of thesteam-chest I connect the casing K, which contains the several workingparts of the attachment, by means of coupling-nut L, and at M connectionis madewith the oil-pipe I.

N is a plug screwed into a bridge O, separating chambers P and P'. Thisplug is provided with a very small passage R and a larger passage R'.The small passage opens into the hollow chamber S of plug N, outlet fromthis chamber into chamber P being provided in the form of two or morerows of holes Si, drilled around the periphery of plug N. The largepassageR opens directly into chamber P'.

, On a circular projection of bridge O is seated the disk valve T,provided with a central stem T', filling the passage R. When valve T isclosed, as in the drawings, the stem T' closes the passage R. Into theperiphery of disk T one or more rows of holes U are drilled. Valve loovT is controlled by screw-threaded stem V and handle V.

It is evident from the drawings that when valve T is closed thelubricant and the steam coming down pipe I must pass from it intochamber P and thence to the steam-chest through holes U, small passageR, holes S, and chamber P. When valve T is opened, removing stem T frompassage R', then direct communication is established between passages Pand P by way of passage R'.

The operation of the attachment in connection with the lubricator andthe steam-chest is as follows: The lubricator having been put intooperation in the usual and well-known manner, oil and steam will passfrom the lubricator, through oil-pipes N and passage R, into thesteam-chest. The constant pressure of steam in pipe I toward thesteam-chest enables the lubricant to force its way through the chokedpassage R, and in case a partial vacuum is formed in the cylinder byshutting off steam therefrom the small passage R arrests the downrush ofsteam through pipe I and maintains the steam at quite 01 nearlya uniformpressure, thus cqualizing the flow of thelubricant under allcircumstances. If for any reason the enginemen desire to use handoilers,with which lubricators are usually provided, to feed intermittently alarger quantity of oil into the cylinder than would conveniently passthrough passage R, or to oil the valves and cylinders in case thesightglasses of the lubricator should break, then valve T is opened,making the large passage R available for such purpose.

The holes U in valve T and the holes S in plug N form strainers at theinlet to and the outlet from passage R. The diameter of these holes isintended to be slightly less than that of passage R, so that any matterwhich will pass through holes U or S will readily pass through R withoutclogging the same. The number of holes U and S should provide an areatwenty to thirty times that of passage R. At the same time each one ofthe holes U or S is preferably large enough to ad mit the passagethrough it alone of the normal volu me of the lubricant through pipe I.It is evident, therefore, that as long as one each of the holes U and Sis open the lubricator cannot be rendered inoperative, and if thestrainers are looked after and cleaned before the engine goes out on arun it is practically impossible that all the holes in the strainersshould be clogged during the run of the engine, and the lubricator willtherefore be eminently reliable and efficient.

The parts of the attachmentare so arranged that the straincrs can be gotat readily whenever it is desired to clean them. It is also evident thatdelivery of lubricant from pipe I through passage R is independent ofthe strainer-holes U, so that even if all the holes U should clog upduring the run of the engine by'opening valve Ta large and independentdelivery-passage is provided for the lubricant from the hand oilers. Inother words, the larger valve-controlled passage R is independent of andextends around not only the permanently open choked passage, but alsothe strainer at the inlet end of said passage,as well as,for thatmatter,the strainer at the outlet end of said passage.l

Having described my improvements and 'the best way now known to me ofcarrying the saine into effect, I state, in conclusion, that I do notrestrict myself tothe structural details herein set forth inillustration of my said improvements, since manifestly thesame can bevaried without departure from the spirit of my invention; but

Vhat I claim herein as new, and desire to secure by Letters Patent, is

l. A lubricator attachment comprising a casing adapted to be connectedto the lubricator and steam-chest respectively and containing apermanently open choked passage, a strainer at one or both ends of thesaid passage, and a larger valve-controlled by-passage which isindependent of and extends around both the choked passage and thestrainer or strainers therefor, substantially as and for the purposeshereinbefore set forth.

2. A lubricator attachment comprising a easing adapted to be connect-edto the lubricator and the steam-chest respectively, and containing aplug N which has a small permanently open choked passage,a strainer anda larger valve-controlled by-passagc which is independent of and extendsaround both the choked passage and the strainer therefor at the outletend of the choked passage, substantially as and for the purposeshereinbefore set forth.

3. A lubricator attachment comprising a casing adapted to be connectedto the lubricater and steam-chest respectively, and containing a smallpermanently open choked passage, a larger by-passage and a valve T whichcontrols the by-passage, and is provided with a strainer for the inletend of the choked passage, substantially as and for the purposeshereinbefore set forth.

4. A lubricator attachment comprising a casing adapted to be connectedto the lubricator and steam-chest respectively and containing alargevalve-controlled by-passagc and a permanently open choked passage,protected at both its inlet and its outlet end by strainers,substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 11th day of March,1899.
